(Cl. Sii-122) 6 Claims.

This invention relates to a harvester thresher of the self-propelled type in which a platform is provided at the front of the separator and extends laterally to each side thereof.

In a harvester thresher of this type, the platform extends laterally beyond the wheel tread of the thresher, and it is extremely diicult to transport the machine.

It is -an important object of the inventionI to provide a self-propelled harvester thresher which may be readily transported.

Another object of the invention is to provide a platform for a self-propelled harvester which is so constructed that it may be folded at its ends, so that the width of the platform may be decreased for transporting the thresher.

These and other objects and advantages of the present invention will be apparent to those skilled in the art after a consideration of the following detailed description of the preferred structural embodiment, taken in conjunction with the accompanying drawings.

In the drawings:

Figure 1 is a top view of the self-propelled harvester thresher embodying the features of the present invention;

Figure 2 is a front view of the self-propelled harvester thresher showing the ends of the platform in their folded position;

Figure 3 is a perspective view of the platform showing the hinge connection therein; and,

Figure 4 is a sectional view taken along the line 4-4 of Figure 1.

Referring now to the drawings, more particularly to Figure l, it will be seen that the harvester thresher 5 is of the self-propelled type and comprises a separator B and a platform 1. The separator 5 is supported on a pair of front wheels 8, and a rear steerable wheel 9.

Above the separator G'is mounted an operators platform I I on which is provided a steering wheel I2, and an operators seat I3: A rod I4 extends rearwardly from the steering wheel |2 and is connected to an arm I5 provided on the steerable wheel 9, so that the harvester may be steered from the operators platform II.

Any suitable type of motor I6 may be mounted on the separator 6, or on the operators platform II, so as to drive the wheels 8 and the operating parts of the thresher.

As shown in Figure 1, a belt I1 is trained around a pulley provided on the motor I6 and a pulley provided at the end of the cylinder I8. A chain I9 is trained around a suitable sprocket A tion 23.

ets 39 and 4I.

provided on the motor I6 and is associated with the wheels 8 so as to drive the same.

The platform 1 consists of a central portion 2|, a righthand portion 22, and a left-hand por- The central portion 2| is provided with a longitudinally disposed conveyor 24 which extends rearwardly. The central portion 2| of the platform 1 is pivotally mounted on a shaft 25 which is journaled on the front of the separator 6. As shown in Figure 4, the central portion 2| is provided with an under-shot conveyor 26 that conveys the grain from the conveyor 24 rearwardly and upwardly into the cylinder I8.

On the right-hand portion 22 of the platform 1 is rotatably mounted an open end auger 22a, and on the left-hand portion 23 is rotatably mountedan open end auger 23a. 22a and 23a are driven through a driving connection with the shaft 25.

Referring to Figure 1, it will be noted that -a chain 21 is Vtrained around a sprocket 28 provided at one end of the cylinder I8 and a sprocket 29 provided at one end of the shaft 25. 'At the other end of the shaft 25 a sprocket 3| is provided. On the central \portion 2| is journaled a shaft 32 on which is provided a sprocket 33.

A chain 34, trained around the sprocket 3| and the sprocket 33, drives the shaft 32.

The central portion 2| of the platform is counterbalanced by the springs 35, which are connected to the operators platform II and the center portion 2|, in front of the shaft 25. The platform 1 is adjusted by the hand wheel 36, from which extends a rod 31 that extends down- Wardly and is connected to the center portion 2|.

The augers 22a and 23a are driven from the driven shaft 32. 0n the rright hand portion 22 of the platform is mounted ashaft 44 at the outer end of which is provided a sprocket 39. A sprocket 4| is secured at the end of the auger 22a, and a chain 42 is trained around thesprock- The inner end of the shaft 38 is releasably connected tothe shaft 32 by a clutch mechanism 43. On the left-hand portion 23 of the platform is mounted a shaft 44 at the outer end of which is provided a sprocket 45. A sprocket 46 is secured to the end of the auger 23a, and a chain 41 is trained around the sprockets 39 and 4|. The inner end of the shaft 44 is releasably connected to the shaft 32 by a clutch mechanism 48. The front edge of the platform 1 is provided with the usual cutting mechanism 49 which consists of linger guards 5I, and a reciprocating sickle 52 that cuts the grain.

The augers yThe rightfhan'dportion .22 and the left-hand portion 23 of the platform 1 are each pivotally connected to the central portion 2| by hinges 53. As shown in'Figure 3, one of the hinges i's provided on the front part of the platform and the `other hinge is provided at the rear of the platform 1. The hinges 53 are positioned on the front and rear of the platform so that their pivot axes are coaxial, as shown in Figure 3 by the line a drawn through their respective axes.

When lthe harvester thresher is in operation,

the platform l is inthe position shown in Figure 1 l. That is, the platform I extends laterally to each side of the separator 6. `'I'he operator controls the thresher from his station I3 on the operators platform ll. The cutting mechanism 49 cuts the grain, and the augers 22a and 23a 'convey the grain onto the longitudinally disposed elevator 24 from which the grain is conveyed .bythe under-shot conveyor 26 into the cylinder of the thresher.

When it is desired t transport the thresher,`

theouter ends of the platform are folded into the position shown in Figure 2. The reciprocating. sickle 24 is removed. Since the augers 22a and 23a are of the open end type, they need not be disconnected from the platform. By open end is meant that the inner ends of the augers 22a and 23a are unencumbered by any shaft or other support, thus leaving a freel space for communication with the conveyor 24, so that cut material is readily transferred lfrom the augers to the conveyor 24. In other words, there is no shaft support for these augers spanning the conveyor 24. vided on the platform 'l in such a location that the open end of the auger will clear the outer ends of the central' portion 2l. The clutch mechanisms 43 and 48 disengage when the righthand and left-hand portions 22 and 23 of the platform are folded. The portions 22 and 23 of the platform are held in their folded position by brace rods 54 which, in the present case, are

4 connected to the central portion 2| and the outer ends of the portions 22 and 23. y

Viewing the harvester from the front, as shown in Figure 2, it is apparent that the width of the thresher is considerably less when the platform is folded. The harvester, by this folding platform construction, may be readily transported at its reduced width. The platform may be quickly fol-ded since only the reciprocating wheel 'I'he hinges 53 are prosupported separator, a platform pivotally mountedat the front of the separator and hav-y ing opDOSlte end portions respectively extending laterally to each' side thereof, and hinge means Y provided in the` platform at each side of the separator for folding the end portions of the platform upwardly towardone another to reduce the length thereof. .A
